TOOL FOR CLAM PING TYPE TO TYPE-BARS.

SPECIFICATION forming part of Letters Patent No. 449,190, dated March 31, 1891.

Application filed October 6, 1888. Renewed September 2, 1890. Serial No. 863,747. (No model.)

To all whom it may concern:

Be it known that I, HENRY ABBOTT, of N ewark, in the county of Essex, and in the State of New Jersey, have invented certain new and useful Improvements in Clamps or Holders for Uniting Types and Bars for TypeWVriting Machines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is an enlarged perspective view of a type and its bar separated from each other. Fig. 2 is a like view of the same when combined. Fig. 3 is a perspective View of the tool used for holding said parts in relative positions for soldering. Fig.4 is a plan view of the same, and Fig 5 is a side elevation of said tool in the position occupied when in use.

Letters of like name and kind refer to like parts in each of the figures.

The object of myinvention is to enable the type and type-bar of a type-writing machine to be accurately held in position for soldering; and to this end my said invention consists in the holder or clamping-tool employed, substantially as and for the purpose hereinafter specified.

My device is intended for use in connection with a type A, which has, preferably, a straight cylindrical form with a letter or character upon one end and a longitudinal slot to within its opposite end. Said slot is for the reception of one end of a bar B, that, as seen in Fig. 1, has at such point one edge I) formed upon an angle, so that when said bar and type are combined, as shown in Fig. 2, such beveled edge will bear upon the bottom of said slot and cause said bar and type to have the relative angles seen in Fig. 5.

For confining the typeA and bar Bin their relative positions for soldering I employ a tool which consists, principally, of a straight metal frame-bar O, that upon one end has secured a handle D and within its opposite end is provided with a half-round or V-shaped notch c, that is adapted to receive said type. Resting in suitable guides upon one side of said frame bar is a thin bar D, which is adapted to be moved longitudinally lengthwise of the same, is provided at its rear end with a curved lug cl, by which such movement is eifec-ted, and at its outer end is curved upward and rearward, so as to cause said end d to bear against the center of the notched outer end of said frame-bar at a right angle to the line of the notch c.

The sliding bar D is held with a yielding pressure at the rear limit of its motion by means of a spring E, which is secured at one end to the side of the frame-bar O opposite to said sliding bar and has its opposite free end passed through a slot 0' in said framebar and connected with said sliding bar. As thus arranged, if said sliding bar is moved outward by the pressure of 'the thumb of the operator against the lug dand a type A is placed within the notch 0, upon releasing said bar from outward pressure the action of the spring will cause said type to be firmly pressed into and held within said notch.

lVhile the form of spring shown is prefen ably employed, any desired construction or arrangement of spring may be used in place of the same.

For the purpose of holding the type-bar B there is attached to one side of the frame-bar C a block F, which has the general form in side elevation shown, and within its upper edge is provided with a groove f, that corresponds in width and depth to the thickness and width, respectively, of said type-bar and has such inclination toward the front end of said frame-bar that when a type-bar is placed in said groove with its cut-away end I) resting within the slot a of a type A non fined at such point said type-bar and type will occupy the precise relative positions desired.

In order to insure the longitudinal position of the type-bar B, the rear portion of the block F is cut away at one side of the groove f, and within the vertical face of the opposite side of said groove is provided a round pin f that corresponds to the pivotal opening I), which is formed in the rear end of said typebar. As thus arranged a type-bar is placed in position by first causing its rear end to engage with the pin named and then turning said bar downward into the groove f and. the slot dot the type A.

When in place within the holder, a type-bar is locked in position by means of a spring G, which has one end pivoted upon the upper side at the rear end of the block F and its opposite curved end in engagement with the upper edge of said type-bar midway between said block and the type A. Said spring is capable of being moved laterally upon its pivotal hearing, so that its front end may be easily placed upon or removed from engagement with said type-bar.

In the use of the tool, after a-type and bar have been placed in position solder is applied to their engaging surfaces and fused by the action of heat, after which said parts are immersed in water and then removed, When it will befound that they occupy the precise relative positions provided for in the construction of the tool and that no deviation therefrom can occur. 7

Having thus fully described my invention, what I claim is- 1. The tool described, in which the springoperated clamp for confining the type in a vertical position, the inclined grooved block for receiving the bar, and the spring for holding said bar within such grooved block are combined, substantially as and for the purpose specified.

2. The tool described, in which the springoperated clamp for engagement with a type, the grooved block for the reception of a typebar, the pin for engagement with the pivotal opening in said bar, and the bar-confining spring are combined, substantially as and for the purpose shown.

In testimony that I claim the foregoing 1 have hereunto set my hand this 21st day of August, 1888.

HENRY ABBOTT. Vitnesses:
